CAR.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed December 7, 1908. Serial No. 466,349.

To all whom it may concern:

Be it known that I, ROBERT DUNNING, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Cars, of which thefollowing is a specification.

I My invention relates to an improvement in platform sup ort for cars.

The object of my invention is to provide means for connecting the trussrod of a car directly to the platform beam.

Another object of my invention is to provide means for suspending theplatform to the end sills.

The features of my invention are more fully set forth in the descriptionof the accompanying drawings, forming a part of this specification, 1nwhich Figure 1 is a side elevation of a platform beam applied to thesill of a car. Fig. 2 is a top plan view of the same with the truss rodomitted. Fig. 3 is a section enlarged on line at, 113, Fig. 1. Fig. 4 isan inside elevation, illustrating the manner of connecting the truss rodto the platform beam.

In the drawings but one beam isshown at I one side ofthe sill, aduplicate form being followed on each side and at each end.

1 represents the side sill and 2 an end sill of the ear.

3 re resents a platform beam, preferably of stee construction, made upof angle iron and plate secured at its inner end to the side sill bymeans of bolts 4.

5 represents an end sill plate secured to the sills, and 6 represents adepending beam supporting bracket, preferably made of angle iron,provided with an inturnod flange 7 resting upon the sill plate 5. Thisbracket is preferably riveted to the sill plate 5and beam 6, asillustrated in the drawing.

8 re resents a truss beam secured and sup- POIiZPIFUPOII the side sill,and 9 represents a truss rod for the side of the car, the ends of whichproject downwardly and are secured to a bracket 10 fixed to the platformbeam 3.

By this construction the downward strains on the platform beam are takenup by the truss rods relieving the ends of the sills from such strain.

This construction makes a very rigid support for the platform andprevents sagging as is experienced in platforms as new constructed.

Having described my invention, I claim In a car construction, a carsill, a platform beam secured to the underside of the sill and rojectedbeyond the end thereof, a vertical lieam extending upwardly on the sill,a truss rod engaging the beam and extended to a position under andbeyond the end of the sill, and means securin the rod to the platformbeam, substantiafiv as described.

In testimony whereof, I have hereunto set my hand.

ROBERT DUNNING. Vitnesses:
